ATTACHMENT FOR GEAIN-SEPARATORS.

Specification of Letters Patent. Patented Sept. 27, 1921.

Application filed February 10, 1920. Serial No. 357,743.

T 0 all whom it may concern.

Be it known that 1, WILLIAM E. Tonnn, a citizen of the United States of America, residing at Pawnee, in the county of Pawnee and State of Oklahoma, have invented new and useful Improvements in Attachments for Grain-Separators, of which the following is a specification.

This invention comprehends the provision of an attachment for grain separators or the like, and consists of one or more perforated pipes extended transversely across the machine in front of the riddles, the pipes being associated with a suction fan or the like so that the chaff or dust will be lifted out of the grain or other cereal, thus preventing overloading of the riddles, and enabling the machine to do more work.

of the openings in the pipe for light or heavy chaff or for dry or damp weather,

while the pipe may also be adjusted vertically with respect to the machine as the occasion may require.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this specification like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a fragmentary longitudinal .section of a grain separator showing the attachment applied thereto.

Fig. 2 is a top plan view.

Fig. 3 is an enlarged detail view of the attachment.

Fig. 4 is a sectional view taken on line 4-4E of Fig. 3.

Fig. 5 is a detail view of the adjustable slide.

Fig. 6 is a view of a modified form.

Referring to the drawings in detail, A indicates generally a grain separator or the like, the attachment being indicated genorally at B. In'the preferred form of the invention the attachment consists of a pipe 10 which extends across the machine at the rear of the grain pan or just in front of the riddles of the machine. The pipe 10 is associated with a fan or the like 11 which is mounted at one side of the machine and operated from a suitable part of the latter by means of the belt 12. The pipe is provided upon its under side with a plurality of open ings 13 which may successively increase in size from the end of the pipe adjacent the fan toward the opposite nd to equalize the suction through the pipe in lifting the chaff from the grain through the openings before it passes on to the riddles. If desired, the pipe may be formed with guide grooves 15 in which a slide 16 is slidably fitted, the slide having openings to register with the openings 13 of the pipe. The openings 17 of'the slide correspond in size and shape to the openings in the pipe, but by adjustment of the slide the openings in the pipe may be varied in size to control the suction for light or heavy chaff. Small pipes 18 may depend from the openings 18 in the pipe and also from openings 19 in the end of the pipe.

The chaff or dust lifted from the grain in this manner tends to lighten the load on the riddles, and also permits the machine to do better work and more work in a given time. The chaff or dust is conveyed through the pipe 10 to the stacker of the separator. The suction pipe 10 may also be adjusted vertically in any suitable manner with respect to the machine for dealing with light and heavy chaff or when found necessary by reason of weather conditions.

In Fig. 6 T have shown a modified form of the invention, wherein a pipe 20 projects from the pipe 10 communicating therewith, the pipe 20 extending in the direction of the forward end of the machine, and supporting a pipe 21 arranged parallel with the pipe 10 and constructed similarly thereto. The pipe 21 is preferably arranged just back of the beater of the machine and by reason of the perforations 22 the suction from the fan or blower will lift the dust and other foreign matter from the straw.

While it is believed that the nature and advantages of the invention will be readily understood from the foregoing description, I desire to have it known that I do not limit myself in this specific connection, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is:

An attachment for grain separators comprising a pipe extended transversely of the guide and having a longitudinal series of machine in front of the riddles thereof, said openings adapted to be moved across the pipe having perforations along the underperforations of said pipe, a pluralityof small 10 side and successively increasing in size from depending pipes projecting from the open- 5 one end of the pipe to the other, guide ings of said plate forthe purpose specified.

flanges secured to the pipe longitudinally In testimony whereof I afiix my signature. thereof, a plate slidably fitted between said VILLIAM E. T OLER.
